Answer:

x < – 3 or x > – 2

Explanation:

For x + 3 < 0 :

subtract 3 from both sides of the inequality:

x + 3 – 3 < 0 – 3

x + 0 < – 3

x < –3

For 5x > – 10:

Divide both sides of the inequality by 5 to isolate x:


(5x)/(5) > (-10)/(5)

x > –2

Therefore:

x < – 3 or x > –2

Interval notation: [(– ∞, –3) ∪ (–2, ∞)]
